Miranda Rights Changing

From Yahoo News:
"High court trims Miranda warning rights bit by bit"

I don't see why they need to change anything in the Miranda Rights. It has worked for decades in giving those who are arrested knowledge into their rights. It seems that the changes are made to protect the police, FBI, etc and not those arrested. I guess we are moving closer and closer to becoming a country where you are guilty until you prove yourself innocent instead of the other way around.
